Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697892, here are decompositions:

3 + 8697889 = 8697892
23 + 8697869 = 8697892
41 + 8697851 = 8697892
59 + 8697833 = 8697892
83 + 8697809 = 8697892
89 + 8697803 = 8697892
101 + 8697791 = 8697892
113 + 8697779 = 8697892

Showing the first eight; more decompositions exist.
